Biocompatible Amphiphilic Hydrogel–Solid Dimer Particles as Colloidal Surfactants

Jing Fan, Esther Amstad

Emulsions of two immiscible liquids can slowly coalesce over time when stabilized by surfactant molecules. Pickering emulsions stabilized by colloidal particles can be much more stable. Here, we fabricate biocompatible amphiphilic dimer particles using a h ...

Interface tuning and stabilization of monoglyceride mesophase dispersions: Food emulsifiers and mixtures efficiency

Several food surfactants were examined as possible efficient emulsifiers for liquid crystalline monolinolein-based particles and as alternative choices to the non-food-grade emulsifier conventionally used Pluronic (R) F127. We described a food emulsifiers' ...

The Intricate Structural Chemistry of MII2nLn-Type Assemblies

Kay Severin, Rosario Scopelliti, Euro Solari, Philip Pattison, Mathieu Jérémie Marmier, Farzaneh Fadaei Tirani, Giacomo Cecot

The reaction of cis-blocked, square-planar MII complexes with tetratopic N-donor ligands is known to give metallasupramolecular assemblies of the formula M2nLn. These assemblies typically adopt barrel-like structures, with the ligands paneling the sides of ...

Influence of Fluorinated Surfactant Composition on the Stability of Emulsion Drops

Michael David Kessler, Esther Amstad, Gianluca Nicolas Etienne

Aqueous drops of a well-defined size are often used as small containers for conducting chemical and biochemical reactions, cell assays and as templates to produce microparticles. To prevent their coalescence, they must be stabilized, for example, using sur ...

Crystalline Oligo(ethylene sulfide) Domains Define Highly Stable Supramolecular Block Copolymer Assemblies

Jeffrey Alan Hubbell, Davide Demurtas, Carrie Ellen Brubaker, Edward Allen Phelps

With proper control over copolymer design and solvation conditions, self-assembled materials display impressive morphological variety that encompasses nanoscale colloids as well as bulk three-dimensional architectures. Here we take advantage of both hydrop ...

Specific Ion Effects in Amphiphile Hydration and Interface Stabilization

Yixing Chen, Sylvie Roke, Rüdiger Scheu

Specific ion effects can influence many processes in aqueous solutions: protein folding, enzyme activity, self-assembly, and interface stabilization. Ionic amphiphiles are known to stabilize the oil/water interface, presumably by dipping their hydrophobic ...

Isocyanoacetates as Synthetic Platform Towards Natural Products and Biologically Relevant Scaffolds

Thomas Bertrand Pascal Marie Buyck

My PhD work started with the development of a racemic access to trigonoliimine B, an hexacyclic alkaloid isolated in 2010. After having explored different strategies, we reported a 7-step synthesis of this natural product. This synthesis features a challen ...

Characterization of Three Amino-Functionalized Surfaces and Evaluation of Antibody Immobilization for the Multiplex Detection of Tumor Markers Involved in Colorectal Cancer

Nicolas Xanthopoulos, Vincent Laporte

Antibody microarrays are powerful and high-throughput tools for screening and identifying tumor markers from small sample volumes of only a few microliters. Optimization of surface chemistry and spotting conditions are crucial parameters to enhance antibod ...

Polymer micelles with pyridyl disulfide-coupled antigen travel through lymphatics and show enhanced cellular responses following immunization

Jeffrey Alan Hubbell, Melody Swartz, Conlin O'Neil, Jackson Eby, Sachiko Hirosue, Karen Dane

Poly(ethylene glycol)-stabilized poly(propylene sulfide) core (PEG-PPS) nanoparticles (NPs) smaller than 50 nm efficiently travel to draining lymph nodes and interact with antigen-presenting cells (APCs) to induce potent immune responses following intrader ...

Vibrational Sum-Frequency Scattering Studies of Oil-in-Water Emulsions

Hilton Barbosa De Aguiar

Oil-in-water emulsions consist of oil droplets dispersed in an aqueous phase. Interfacial properties of the droplets determine the stability of emulsions. Even though this statement is widely accepted, a molecular level picture of the droplet interface is ...
